Features and advantages of cutter suction dredger


(1) The cutter suction dredger is widely used and can be used in rivers, lakes and seas for dredging, channel excavation, and land reclamation. Under special circumstances, high-power reamer equipment is installed on cutter suction dredgers to excavate rock formations such as basalt and limestone without blasting.


(2) The cutter suction dredger is economical. The excavation and transportation of materials can be completed at one time, without the cooperation and multiple handling of other ships. Relatively low engineering cost. The twist output is large and the pump distance is long. The output of large cutter suction dredgers can reach several thousand cubic meters per hour; the sediment or crushed rock materials are pumped out several kilometers away by means of powerful power through the mud pump and the mud discharge pipeline.


(3) The cutter suction dredger is simple to operate and easy to control. The dredger relies on the trolley at the stern to position and step the steel piles, uses the two-measurement steel cables of the reamer boom and the anchors fixed to the two-measurement of the dredging groove, and is pulled by the winch, and the hatchback swings to cut the sediment material. Work under a certain control swing angle, and pump the twisted material to the accumulation yard through the mud conveying pipe. The stepping of the dredger is alternately moved by two piles, stepping forward.


(4) The large cutter suction dredger is equipped with a self-propelled system. It can be self-propelled in place during migration. Most of the small and medium dredgers have no self-propelled system and are towed by tugboats. Small and medium-sized dredgers can be designed and built to be assembled, transported to the site by land, and can be used after assembly.


(5) The cutter suction dredger is economical. The excavation and transportation of materials are completed at one time, without the cooperation of other ships, and several times of handling. Relatively low engineering cost.
